Defective quality printed image copy identifying method for print substrate, involves determining location of copy containing defect by comparing data, correlating with image, to data record concerning arrangement and form of copy

摘要

The method involves capturing an image of a part of a print substrate (03), and analyzing data that correlates with the captured image to determine whether a defect that reduces quality of the image exists on the substrate. Location of a copy containing the defect is determined by comparing the data, correlating with the image, to an electronically generated data record concerning arrangement and form of the copy in the substrate.
